TL;DR: Experience with the algorithm on small problems indicates it converges exceptionally quickly to the optimal answer, often in as few iterations as are needed to perform a single simulation with no optimization using more conventional approaches.
Abstract: Based on recent work by Powell, a new optimization algorithm is presented. It merges the Newton-Raphson method and quadratic programming. A unique feature is that one does not converge the equality and tight inequality constraints for each step taken by the optimization algorithm. The article show how to perform the necessary calculations efficiently for very large problems which require the use of mass memory. Experience with the algorithm on small problems indicates it converges exceptionally quickly to the optimal answer, often in as few iterations (5 to 15) as are needed to perform a single simulation with no optimization using more conventional approaches.

TL;DR: An Integrated Reliability Optimization Model that includes both of these two methods for improving the reliability of a system is presented and it is shown that under certain assumptions the integrated model reduces to a Redundancyoptimization Model and under certain other assumptions reduces to an Design Optimization model.
Abstract: The two traditional methods used in improving the reliability of a multi-stage system are examined The first method is the creation of redundancy in system components, whereas the second method consists of overdesigning the system components An Integrated Reliability Optimization Model that includes both of these two methods for improving the reliability of a system is presented It is shown that under certain assumptions the integrated model reduces to a Redundancy Optimization Model and under certain other assumptions reduces to a Design Optimization Model Several methods that have been previously suggested for obtaining solutions to the Integrated Optimization Model are reviewed and a generalized solution procedure for such a model is presented This solution procedure involves the successive solution of two subproblems a number of times The first subproblem is a design optimization problem that is solved by the Davidon-Fletcher-Powell optimization algorithm The second subproblem is a reliability redundancy optimization problem that is solved with the heuristic approach of Aggarwal, et al

TL;DR: In this article, the on-line optimization of a liquid extraction process using a model-based scheme is described, where four steady-state process models are first investigated for their ability to predict the process performance; these models are subsequently used in the optimization study.
